• 5 programs with 4 segments each can be saved

• Precise temperature control

• Solar Mode for using energy from photovoltaic systems with or without storage with specially tuned control behavior for delayed switching times of solar storage (from V2.0)

• Max. 2 segment-wise, switchable functions for controlling additional electrical equipment

• Increased process reliability due to different operator levels

• 24 languages selectable

Information menu with status messages

• Adjustable alarm functions, e.g. for temperature behavior

• WLAN module for connection to the MyNabertherm app

• USB interface for import and export of data
